标准摘要
[中文适用范围]： ISOIEC 23001 的这一部分规定了片段请求单元技术。 它包括用于表达对 XML 片段的请求的语法和语义。 它还指定如何在基于 XML 的系统（例如 ISO/IEC 15938-1 和 ISO/IEC 23001-1）中使用此类请求。 该技术可用于资源受限的环境中，以便仅在给定时间感兴趣的 XML 片段需要从响应对等方传输到请求对等方。 它还可以用于远程 XML 文档的逐节点导航。 [外文原描述]： ISO/IEC 23001-2:2008 specifies the Fragment Request Unit technology. It comprises a syntax and semantics for expressing a request for fragments of XML. It also specifies how such requests can be used in XML based systems such as ISO/IEC 15938-1 and ISO/IEC 23001-1. The technology can be used in resource constrained environments so that only the fragments of XML of interest at a given time need be transmitted to a requesting peer from a responding peer. It can also be used for node-by-node navigation of a remote XML document.
